実験手順
In chloroform (10 ml) was dissolved 2-cyclopropyl-4-hydroxymethylthiazole (0.9 g), to which was added dropwise, under ice-cooling, thionyl chloride (0.68 ml), followed by stirring for 30 minutes at room temperature. Excess thionyl chloride was distilled off under reduced pressure. To the residue was added diethyl ether to yield 2-cyclopropyl-4-chloromethyl thiazole hydrochloride (1.1 g) as pale brown powder. m.p. 108°-110° C.
